You still didn't explain yourself. So i will ask you again; Are you saying frequent changes harms the enviorment? If so then i have only one response. :clueless: Ever heard of re-cycled oil? http://www.oilrecycling.gov.au/what-happens.html

Re-cycled oil reduces the impact on the enviroment but still uses resources to re-cycle. You know that don't you?:confused:

:confused: ...these threads invariably get twisted and morph into
some kind of arm wrestle: :rofl: .

I stand by my original post, which was, imo, a valuable link,
and my opinion sprinkled in my original post.

Race cars are just that; our daily drivers are not.
Fuel dragsters get their oil changed after every run.
So what.

I don't care if one changes their oil weekly, but it's a fookin
waste of money and oil, imo.

As for the "environment", my guess is the case of bottled
water someone drank last week has more of a carbon footprint
than weekly oil changes...

These Xs are cars; drive the sumbitches and enjoy 'em. :thumbup:
Change the damn oil as often or, as seldom as you like...
GL,mD

so does the existence of a blue and a goodman.. :rofl:

and so does the CO2 that you breathe out.. what's your point?? :confused:

:iagree:

While the oil may still be good after 3000 miles, I'm not so sure I trust the oil filter to continue to do it's job.

Oil changes every 3k = cheap insurance for anything I care about and want to keep for awhile.

For a lease, fuhgeddaboutit.

The Toyota I own, I change the oil every 5,000 miles.

The BMW is made to go further on a oil and I probably would change it every 10,000 miles. However I lease so its once a year for free.

BMW designed the filter for approximately 16000 miles (depending on your type of driving) or two years. It has safety margins built into that design. Let's conservatively say that there is a 1.5 safety factor. That means 24,000 miles as a design target. I have a hard time believing that the same engineers who designed the engine are out by a factor of 8 on the oil filter.

At the end of the day, I am with MD, do what you like, and just drive it. However, anyone who wants to use up a finite natural resource at 5 to 8 times the rate required should pay an appropriate tax, IMO. If this was fuel (which comes from the same base) then it would be equivalent to driving a car that gets 2.5-3 mpg, and considering that acceptable.
